Find all the second partial derivatives. v = e5xey

Helga [31]3 years ago

I'm taking the liberty of editing your  function  <span>v = e5xey:  It should be 
</span>
<span>v = e^5x^ey, with " ^ " indicating exponentiation.
</span>
Did you mean e^(5x) or (e^5)x?  I'll assume it's e^(5x).

The partial of   v = e^(5x)e^y with respect to x is e^(5x)(5)*e^y, or 25x*e^y.

The partial of v = e^(5x)e^y with respect to y is e^(5x)e^y.

Find the surface area of the square pyramid shown below.​
Katarina [22]

Answer:

The surface area is 40

Step-by-step explanation:

It is 40 because you have to find the area of each face so you would do 3*4 which equals 12 and since there is 4 of the triangles you do 12*4 which is 48 but when it's a triangle you have to cut it in half so it would really be 24.

Then for the square on the bottom you would do 4*4 which is 16 and then you would add the totals to get 40.

Write an algebraic expression to represent the area of the shaded region.
tamaranim1 [39]

Answer:

4y^{2}+3y

Step-by-step explanation:

First you need to distribute the values.    

(4y+3)(2y) Using the "Rainbow Method" to multiply the polynomials    

You Should get    

8y^{2}+6y    

Since this is the area of the rectangle and we need to find the area of the shaded region you need to dived 8y^{2}+6y in half because the shaded region is half of the rectangle.    

8y^{2}+6y/2    

Doing this you will get    

4y^{2}+3y

99 points answer fast!!!!
Katena32 [7]

Answer:

Step-by-step explanation:

So given the three bits of information you can conclude a couple of things. The end behavior towards the right should be increasing and since there is only two turning points this means it was previously going down but had a turning point and starting going up, and before that it was going up and then started going down, those will be the two turning points. So on the left side it should be decreasing and the right side it should be increasing. The last peace of information tells you that at the second turning point, should be equal to 250k when it turned back up OR the y-intercept is 250k. Given all this information the answer should be the first graph in the first picture
